But if you deviate after clear proofs have come to you, then (2:209)

﴿فَإِن زَلَلْتُم مِّن بَعْدِ مَا جَاءَتْكُمُ الْبَيِّنَاتُ فَاعْلَمُوا أَنَّ اللَّهَ عَزِيزٌ حَكِيمٌ﴾
[ البقرة: 209]

2:209 But if you deviate after clear proofs have come to you, then know that Allah is Exalted in Might and Wise.

If you slip up or go astray after clear proofs have come to you, then know that Allah is Mighty in His ability and power, Wise in His planning and establishing of sacred laws.
So, fear and glorify Him.

Then if you slide back after the clear signs (Prophet Muhammad SAW and this Quran, and Islam) have come to you, then know that Allah is All-Mighty, All-Wise.
